Blast winds down its L2 as costs outrun revenue, testing rollup economics

Blast announced on Friday that it will be closing down its Ethereum Layer 2 network and returning its users back to Ethereum mainnet, claiming that keeping the network running is more expensive than its earnings.

The decision has raised questions for the smaller rollups in the already over-crowded L2 space: can small rollups generate enough real activity that can justify their operation?

Blast mentioned that the numbers were not looking promising and stated that the overhead cost of keeping the network running had become larger than the income being derived from the L2.

From $2 billion in deposits to $32 million

Blast made its debut in November 2023 after securing a funding round worth $20 million from investors led by Paradigm and Standard Crypto. Before its mainnet launch in February 2024, the project had secured over $2 billion in funding from almost 200,000 early users, helped by native yield on ETH and stablecoins.

Since then, the figures have dramatically dropped. As of today, DeFiLlama reports that Blast has a DeFi TVL of around $32 million. On the other hand, L2BEAT lists about $38 million secured by the platform and states that its fraud-proof system is still under development.

The BLAST token also fell 17% on Friday, cutting its market value to about $23 million, according to The Block.

When annualized fees run to $755,500 and revenue to $22,700

The imbalance is clear in Blast’s own economics. DeFiLlama recently showed about $755,500 in annualized fees but only around $22,700 in annualized chain revenue.

That is the real problem: bringing money onto a network is one thing; however, getting enough constant transactions that would make keep that network operating is quite another.

Cheaper blobs did not fix the math

Blast also operated during a period when Ethereum had already reduced one of its key rollup costs. By introducing blobs as part of EIP-4844, Ethereum enabled L2s to transmit data at a much lower cost than traditional calldata. According to Ethereum’s Danksharding plan, blob data is temporary and will be deleted from nodes after about 18 days.

Blast’s shutdown shows that reducing one major operating cost can help, but a network still needs enough activity and revenue to sustain itself.

A shakeout that keeps widening

Blast forms part of a bigger contraction. As was stated earlier by Cryptopolitan, three blockchain projects suspended their operations on the same day in May. Rollup value locked, that had a peak of more than $50 billion in October 2025, has dropped by around 36% since then, while Arbitrum One, Base, and OP Mainnet are estimated to hold almost 75% of the entire activity.

The weakness is not limited to L2s alone. A recent count by RootData, cited by Tangem, claimed that more than 99 blockchain projects closed in the first six months of 2026.

Exchanges move before the lights go out

Upbit and Bithumb moved quickly after the announcement, designating BLAST as a trading-caution asset. Bithumb’s notice cited concerns about sustainability and the end of mainnet operations.

Blast will first withdraw its Lido holdings, a process expected to take about a week. Users can withdraw through Blast’s interface until October 26, after which they will need to use its Ethereum bridge contracts directly.

With only about $32 million left in DeFi TVL, the shutdown is unlikely to threaten the wider market. Its bigger message is about L2 economics: cheaper infrastructure only goes so far when users, activity, and revenue do not follow.
